[edit] Summary

french translation of Buck_continuous_discontinuous.png by Cyril BUTTAY

graph Us=f(Is) of a buck converter. This figure has been made using gnuplot 4.0 with the following source (released as belonging to the public domain):

# This file is used to plot the domains of continuous and
# discontinuous operation of a buck converter

# graph configuration
set terminal postscript eps enhanced "Times-Roman" 24
set encoding iso_8859_15

# normalized voltage=g(normalized current)
f(x,D) = 1/(2*x/D**2+1)
g(x,D) = f(x,D)<=D?D:f(x,D)
x1(t) = t

#parametric functions for plotting of domain limit
set parametric
my_x(t) = (1-t)/2*t
my_y(t) = t

set output "buck_continuous_discontinuous_french.eps"

# the plot is set as parametric, so each curve is defined by two values: x,y
plot [0:1][0:0.25][0:1] t,g(t,0.1) ls 1 title '', \
        t,g(t,0.3) ls 1 title '', \

Then it is converted in png format using the following command (Linux):

convert -density 300 buck_continuous_discontinuous_french.png buck_continuous_discontinuous_french.png
